original lucas turn switch on late 289/427's

[rsk289]

That looks like a standard MkII Mini switch. The slightly later switch is still readily available new from any Mini supplier, the only difference being that the later switch has a black button in the end. All MkII Minis had the chrome button - the button unscrews as the horn spring is behind it - you can either swap in a chrome button from an earlier switch, or strip the black and polish.
